Question / Help Ryzen 2700x on 1080p60 @ Slow possible ? Encoding Overloaded...?

[zampanotv]

Hello,
I want 2 know if its possible to stream @ 1080p60 on Slow Preset with my Ryzen 2700x.
1080p60 medium works fine when I capture my Switch Gameplay but @ slow preset -> Encoding Overloaded ... at ~50% CPU Usage.

Is it possible to more than ~50% off my CPU and choose a lower preset than medium ?

I dont know why, but the stream quality isnt that good with 1080p60 medium @ 6000kbit/s

I think you are facing two limits here.

1) 6 Mbit/s is too low for 1080p60 to be super good. For comparison - Bluray discs come at around 36 Mbit/s and they are not encoded live.
2) H.264 encoding doesn't scale linear. Just throwing more cores at it won't work. Some processing steps will cause a bottle neck.

Ok 1) seems possible.
Should I Stream on 720p60 (Slow) with 6Mbit/s or 1080p60 (medium) with 6Mbit/s for good quality ?

2) So do u think for normal Streaming on Twitch a Ryzen 2700x is enough for the money ?
Because I think the Quality wont be better when I buy a Threadripper for example, so between the 2700x and the Threadripper wont be that much difference right ?

At 6 Mbit/s I would always go 720p. Maybe you can get away with 960p too. Depends on the motion of the game and what you consider as good quality. Dpedning on the game, maybe you don't require 60fps at all. A good Civ streams can be fine with 30 fps for example.

The Ryzen sounds fine. I don't know if a Threadripper would give any benefits. I doubt it but I cannot try it. Probably a quad core with higher clock speeds is more optimal - but maybe the difference is not that high. A bigger difference may be using NVENC and using a recent GPU instead of a CPU. These are made for 1080p60 I believe. They wont't solve the 6 Mbit/s problem though.

Then again I doin't have any benchmarks what is the "best" setup in this case. It just personal guess work.

So the computer is only dedicated for Streaming not for gaming. Is there a Quad Core with a higher clock better than the Ryzen 2700x?

I tried some tests yesterday and the quality seems good @ 720p60(SLOW)

NVENC is fine for people with only one computer setup, in my opinion.

NVENC isn't bad for streaming PCs too. I would not bother giving up on the 2700x, it is a great CPU. Only if you get a > 5ghz system it may (or may not) worth investigating.
